Weren't you EFI?? With the Sniper I could tell you why it's doing that and how to fix it. There was a discussion about that in the EFI section with good explanation as to why.

If it's a carb, I'd need to know what carb.

Knowing ignition timing helps in this scenario to some degree.


But initial thoughts are simply a lean stumble. Very common when whacking the throttle as you create a big hole and not enough fuel to fill it is the simple explanation. A new combo will take some tweaking to make perfect.
